I’m remodeling a 1950’s bath where all of the DWV is plumbed with 3″ copper. I need to extend one of the arms of the stack with a Fernco to new PVC. What’s the best way to cut large copper tube without a huge tubing cutter? My first thought was a sawzall with a metal blade, but would an angle grinder or maybe even a dremel work better? I'm really worried about deformation and maybe even tearing this stuff as I cut it.
